thanks all

i deleted the
enable_interrupts(INT_TIMER0);
enable_interrupts(INT_TIMER1);

from interrupts and but that in RUN loop

void run(speed,rest)

CCS compiler version. 4.014

void run(speed,rest)
setting 'speed' ;'rest'
are initial value in main() . run(55,5)

hmm...
first delay is this..
delay_ms(500);

you say 'rest' delay is really 10 seconds, so that's 20X longer

That could be the clock isn't really running properly.

I suggest you code/compil ...

When the problem occurred after changing the pic on the same PCB and on the same motor
I took into account the differences between them and I changed Timer 2 to Timer 3. Change #int_rb to #int_E ...

Use pic16f887 to control of ac motor. The code is work fine
but when use pic 18f4520, find two problems:
1- the program is randomly restart (not rest)
2- the value of delay is different at practic ...

OK run good

now at start freq is zero or no signal output is zero. then freq is vary and output is reading the freq

but when freq return zero or no signal . output not zero and still at last v ...

when change some lines as below.
the output is reading frequency input correct.
but when freq is not in range 40Hz to 250Hz . the output is incorrect

what is error
input freq rang is 20 to 10 ...

the output still zero.at any frequency.
but when use 16f877 the output is reading input frequency

version 4.014

i use this program by 16f877 and it play good
but when change to 16f887 not work.

Hi all
Anyone knows why this code not works.
I use 16f877 to control of motor speed using feedback of tachometer signal.
#use delay(clock=4000000,restart_wdt)
#ROM 0x3ff = {0x3478 ...

Hi
Thanks RLScott
I'm not lazy but I try to make dimmer by PIC to control in AC motor since long time.
I try you said and I change a lot of function but i not understand more functions because i us ...

hi
pls
i want to mak a lamp dimmer by use 12c508 .i find this code in microchip site but it not written by CCS how can convert to CCS compiler

#pragma option v;
#include <12C508.h>
/* ...

hi all
any one have answer or help?

hi all

i find the program in microchip site make a dimmer but this program use PIC12c508 I try convert it to PIC16F877A but it not play
how can use this way by PIC16f877a to control in ac motor? ...
